Orthophosphoric acid (Phosphoric acid, orthophosphoric acid, E338)
Orthophosphoric (phosphoric) asidhi ikomboni kubva muchikamu che inorganic, isina kusimba acid. Muchikamu chinogamuchirwa chechikafu chekuwedzera, orthophosphoric acid ine kodhi E338, ndeyeboka re antioxidants (antioxidants), uye rinoshandiswa seacidity regulator.
Kemikari fomula H3PO4. Pakutonhora pamusoro pe213 ° C, inoshandurwa kuita pyrophosphoric acid H4P2O7. Yakanyatso nyungudika mumvura.
Hunhu hwese hweE338
Orthophosphoric acid ine zvinotevera zvimiro zvemuviri - chinhu chekristalline chisina ruvara uye hwema, chinonyungudika zvakanaka mumanyungudzi emvura, anowanzo shandiswa muchimiro chemvura ine mvura (85% aqueous solution ye orthophosphoric acid). Orthophosphoric acid inowanikwa kemikari kubva ku phosphate kana nehydrolysis (calorizator). Orthophosphoric acid inoratidzirwa nemutengo wakaderera (kana uchienzaniswa, semuenzaniso, ne citric acid), saka inowanzo shandiswa mukugadzirwa kwechikafu nezvinwiwa.
Kukuvadza kweOrthophosphoric acid
Mhedzisiro yakashata yeE338 pamuviri wemunhu ndeyekuwedzera acidity, nekudaro kukanganisa acid-base balance, saka zvigadzirwa zvine E338 zvinofanirwa kushandiswa nekuchenjerera kwakanyanya kune vanhu vane gastritis vane acidity yakanyanya, zvakanaka-kuvabvisa kubva mukudya. . Sekureva kwavanachiremba, Orthophosphoric asidhi ine pfuma yeleaching calcium kubva mumuviri, iyo ine yakanyanya kusarudzika pamamiriro ezino enamel uye bone tishu, zvichikonzera caries uye osteoporosis. Kunyanya kushandiswa kweE338 kunokonzera kusagadzikana kwegastrointestinal, kusvotwa uye kurutsa.
Kushanda kweE338
Semugadziri we acidity, Orthophosphoric acid inoshandiswa muindasitiri yechikafu kupa zvigadzirwa kuvira kana kuvava zvishoma. Inoshandiswa mukugadzirwa kwecarbonated soft drinks, cheeses yakagadzirwa, mamwe marudzi ezvigadzirwa zvemasoseji uye hupfu hwekubheka.
Kumwe kushandiswa kweOrthophosphoric acid: mazino, cosmetology, avhiyesheni uye mishonga maindasitiri, kugadzirwa kweanoshambidza uye ekushandura ngura. Mune zvekurima, Orthophosphoric acid chinhu chemarudzi mazhinji efetiraiza.
Kushandiswa kweE338
Panharaunda yenyika yedu, kushandiswa kweOrthophosphoric acid inobvumidzwa, kutevedzera iyo yakanyanya kutenderwa mitemo yekushandisa inosungirwa.
